System and method for protecting user privacy by misleading network sniffing tool in smart home environment

Abstract

The invention provides a system and method for protecting user privacy by misleading a network sniffing tool in a smart home environment. The system comprises a network feature learning module, a privacy protection strategy making module and a network data packet injection module. Based on a data packet sniffing analysis technology and a data packet injection technology in a wireless network environment, the system can independently run in third-party hardware, and can be conveniently and quickly deployed in a smart home environment. Any part of the smart home environment is not modified, normal operation of the smart home environment is not affected, any external support is not needed, the flexibility is high, and the adaptability is high. According to the invention, a false user is simulated in a real smart home environment by injecting a wireless network data packet. Because the simulation strategy is based on the network feature information in the real smart home environment, the simulated false user is not different from the real user and cannot be distinguished and identified by an attacker, thereby achieving the purpose of protecting the privacy of the user in the smart homeenvironment.

Description

technical field [0001] The invention belongs to the field of network technology, and relates to a mechanism for protecting user privacy in a smart home environment, in particular to a system and a method for misleading network sniffing tools by injecting false network data packets. Background technique [0002] With the development of Internet of Things technology and automation control technology, the application of smart home is becoming more and more extensive, and its market size is also growing. A smart home environment consists of one or more smart home management platforms and several IoT devices. IoT devices usually have specific functions, such as controlling device switches, detecting user status, measuring temperature and humidity, and so on. The smart home management platform manages and integrates the functions of these devices through the Internet of Things technology and automation control technology, which can bring convenience to users.

Problems solved by technology

However, applying the above technologies in a smart home environment is difficult and inefficient

The low computing power and low power of IoT devices are not enough to support rectification or data packet injection, and the network delay caused by a fixed network rate is fatal to IoT devices

In addition, in order to introduce rectification technology or implement data packet injection, it is necessary to modify the IoT device itself and the smart home platform in terms of device firmware, network protocol, and platform architecture. This is a complex and labor-intensive task.
